Loops: Iteration, Repetition and Nested Loops
Repeat code without rewriting it, then control exactly when a loop stops and nest loops within loops.
- Loops That CountBy the end you can replace a repetitive program with a repeat block, keep and trace a counter inside a loop, and build a loop that runs until a test is true.
- Robo's PatrolBy the end you will have built a nested loop that patrols several laps, a loop that runs until a battery is low, and a rover that walks a grid and finds its own way home.
